Abstract

Procedimento per il recupero delle soluzioni di incisione dei metalli spente, comprendente gli stadi di:1) estrazione degli ioni del metallo dalla soluzione di incisione spenta per mezzo di uno scambiatore di ioni;2) lavaggio del liquido scambiatore di ioni per mezzo di acqua;3) vaporizzazione dell'acqua di lavaggio;4) cristallizzazione del concentrato dopo la vaporizzazione;5) filtrazione della soluzione di incisione rigenerata;6) ripristino della qualità della soluzione di incisione;7) riestrazione del metallo dallo scambiatore di ioni carico di metallo;8) lavaggio del liquido scambiatore di ioni;9) neutralizzazione dell'acqua di lavaggio;10) filtrazione dopo la neutralizzazione, e 11) recupero elettrolitico dei metalli.
